Hui ink, used in traditional Chinese calligraphy and painting, is rich in variety. There are 14 categories and more than 1,000 varieties of this local specialty ink produced in Huizhou, Anhui Province.
With a strong fragrance, Hui ink is very silky, and the calligraphy and painting from it do not fade.
As one of the "Four Treasures in a Chinese Study," the history of Hui ink can be dated back to the Tang Dynasty (618-907). There are 11 steps in the ink-making process.
In 2006, the craft of Hui ink making was listed in the first group of National Intangible Cultural Heritages.
